If you had read our post few days ago regarding the coating and formula guide team will visit this coating show, we did visit it indeed, but we are kind of disappointed with the small size of it. A visitor  informed that he can "finished" checking most of the booth in 30 mins as there are not much exhibitors. Multi National Company like Ciba is not participate in this coating show.

Well, if compare the Chinacoat,  this Asia Pacific Coating definitely unmatch in term of its number of exhibitors and visitors. Let hope that the next Asia Pacific Coating Show at Bangkok will have more booth and visitor.

This year, the Asia Pacific Coatings Show will be held at Kuala Lumpur, Malaysia. The venue for this coating show is Kuala Lumpur Convention Centre, which is very near to the famous Petronas Twin Tower.

 

Petronas Tower

The show will start next week on the 24th June til 26th June. Of course not to be missed is the coating conference held every year during the coating show. This year, the conference title is"Organic Coating:New  Performances and Developments". Do check out the conference material by BYK , Worlee and Rhodia respectively.

Visitor can pre-register online or register on the spot during the coating show. Registered guest will be provide a tag which can be use during the 3 days of the coating show.

Coating Formula Guide team will attend this coating show and will collect the latest coating technology information, new raw material and many more from this coating show. Do check out for more post from us!!

Do You dislike high gloss finishes? What is the required to lower the gloss?

  

White powder

 

The most common way to lower the gloss is to use matting agent. The matting agent can be in the form of powder which required paint supplier to disperse it, and it is also available in pre-dispersion form. The following are the common types of matting agent:

COLOR CHANGING PAINT TECHNOLOGY

Would you like your paint to be able to change it color under specified condition?
How about market this paint color change properties as value added feature for your paint???

Sound too good to be true? Well, color changing technology is nothing new. What cause the color change?
The main secret to the color change come from the specific pigment properties. The color change is not because the pigment show poor durability or chalking, the color change is because the pigment react to certain condition apply to them.

There are 3 main types of pigment that involve in the color change technology:

1) Photochromic pigment
2) Thermochromic pigment
3) Electrochromic pigment

Photochromic pigment is sensitive to light. A photochromic pigment  will change from transparent to a color when
it is exposed to light, and revert to transparency when the light is dimmed of blocked. Reversible photochromic work by changing their chemical structure after absorbing UV light. The UV light causes the photochromic to absorb color and then change back to clear when the UV source is removed.They can be cycle thousands of times depending upon the application. This pigment can also change from one colour to a different colour by combination with a permanent pigment. The reversible photochromic has been in the color changing lenses for sunglasses. They are also found in the novelty application such as cosmetics, toy and industry applications including paint. They can be applied in the smart energy efficient windows and information display panels. They can control visible light and solar radiation levels passing through them and by carefully formulating, we can regulate the illumination levels, heat gain and heat loss and  this help to better control the interior temperature of a building.

Thermochromic paint and coating change conformation when certain temperature is applied that cause them to change color. This materials have been used in temperature sensitive tape. The color change can be reversible and irreversible respectively.

Electrochromic pigment is apply to paint that change its color with the help of electricity. In short, the paint required an electrical current to change color. The electric current creates special crystals at the surface that can change color depending on the voltage. This only works on metal because a conductive material is required. When the power is removed from the paint, the color change back to its original color. This technology can create every color the human eye can differentiate, with the simple flip of a switch. This technology has been apply to car paint. Would like you car to change color at your wish? This sound like the James Bond 007′ car that can change color.

Tip#1: Try those color change pigment with normal pigment to create different color changing shade.

Tip#2: If durability is required, please use color change pigment instead of dye.

Tip#3: Study how many cycle the pigment can change its color before launching your products.

Evonik, had launch new grinding vehicle resin called Synthetic Resin EP-UC. It is a polyester ketone resin with pigment affinic groups. This resin had universal compatibility, workable on CAB, NC, polyamide, polyester, melamine, epoxy , alkyd polyolefin. It also shows universal solubility in both the polar and non polar solvent.

What is so unique about this resin is that it can be use in both water and solvent base!!!!
It is use to prepare:

1) solid pigment concentrates
2) Water based pigment concentrate diluted with water/water based resin
3) Solvent based pigment concentrate diluted with solvent/solvent based resin
4) Solvent based pigment concentrate diluted with water/water based resin
5) Water based pigment concentrate diluted with solvent/solvent based resin

What Is Paint Stripper?

Paint stripper is designed to remove paint and other finishes on a particular surface. It is also known as paint removal agent.

How It Works?

Paint strippers come in a liquid, or a gel form . Thickener is added to the formula to cause the thixotropic effect, this will help the mixture to form gel that adheres to vertical surfaces, it also reduces the evaporation of the solvents, thus prolonging the time the solvent can penetrate the paint.

It penetrates the paint film by the molecules of its active ingredient, causing its swelling and increase in internal strains, this lead to weakening of the layer’s adhesion to the underlying surface, and thus causing the separation of the layer of the paint from the substrate.

Why adhesion promoter? Sometime poor adhesion do happened between the coating and its direct substrate or it can be a problem of inter-coats adhesion. The usage of adhesion promoter is use to solve this problems.

There many types of adhesion promoter for different application and substrate respectively. Some are suitable for plastic substrate, while some are suitable for metal. The common types of adhesion promoters are:

1) acid derivative type

2) silicone type

3) resin type like polyester

Yes, that’s right, www.coatingformulaguide want to hear from you. We would like to know your comments, ideas and suggestions to improve this website to a new level.

You are encourage to submit your idea via the contact form which is available on this website or you can email us at admin@coatingformulaguide.com. Please note that we will treat your contribution in a "private and confidential" manner.

Below are some of the suggestion we received so far, you can provide more comments to the topic below or advise on new topic:

1) Free formula?
At the moment, we only provide formula guide, not fully provide 100% of the formula concern. This is still the main principle and concept for this website. It is a platform aim to help the paint formulators with formulation tips but not provide formula blindly.
