Polyimide for Buffer Coatings and Interlayer Dialectric

Polyimide is known as a polymer of imide monomers. It is abbreviated as PI, and has been produced massively since 1955. Polyimides are applied in many ways for harsh organic materials such as displays (gadget screens), military tools, and other semiconductors because of their high heat-resistance. Polyimide formulations contain solvent. Instead of adhesive glue joints, polyimides are better for large surface areas. The flame resistance of polyimides make them chosen more often than other similar glue coatings. This makes polyimides safer and more accepted in trading because trade forbids flame retardants strictly. Antimony compounds and red phosphorous structures are not found in polyimides.

Polyimide coatings have sufficient adhesion to the primary surface, judging from an abrasion test. They are slightly stronger than epoxy glue joint. They are applied in many industries that produce things we use daily. For example, Polyimide is used as a coating for the image sensor in such gadgets as a digital camera and cellular phone. It has high transparency and controlled refractive index. It minimises the light loss to reach photodiode. Applications of Polyimide Coatings are also including wire covering, buffer coating, Re-Distribution Layer(RDL) or dialectic layer, and display (gadget screens).

Japan is Asia’s number one polyimides producer. One of the manufacturers creates an aromatic polyimide pioneer solution as the result of their extensive experience in polymerization and application technologies for both polyimides and photosensitive polymers. This high-heat and crack resistant polyimide coatings have excellent film elongation that avoids cracks against bending. Their excellent adhesive strength with various base materials can be achieved by adequate surface treatments. They barely reduce weight at high temperature that enables high heat resistance whose level is equal to non-photosensitive polyimides. They also have high electrical insulation and wide production line, which offers both positive and negative working types.


How silicone resins improve your quality and ease the applications of your paints?

Silicones consist of a backbone of altering atoms of silicon and oxygen known as a siloxane linkage (Si-O-Si) 

and it is commonly used in paint and coating industries to ease the applications of paints. They are produced in a lot of forms including silicone fluids, resins, liquid rubbers and solid rubbers and used in a wide range of industries. Silicone plays various crucial roles in each industry and coating industry is one of them.They are used for base resins in the paints as a main component, silicone powders as additives and silane as pigments and fillers. 


Here are the advantages of silicones in paint and coatings to improve the quality and ease the application of your paint;

1.       Have better resistance to high temperatures

Silicone resins have better resistance to high temperatures than the organic resins. It improves the durability of paints and coatings and reduces the volumes of paint used over the lifetime.

2.       Can aid in wetting, flow and levelling

Many things can go wrong when a coating is applied and dried and in many of these cases it is due to surface tension gradients that arise from temperature and concentration gradients; these surface tension gradients are likely to cause surface imperfections upon film drying. By lowering the overall surface tension of liquid coatings, silicone additives can aid in wetting, flow, and levelling

3.       Better electrical insulation

Silicone resins are very consistent across a wide range of temperatures while organic resins decline in hot and humid conditions.

4.       Flexibility

Silicone resins are easy to apply

5.       Have excellent water resistance

In organic resins, absorbed water does not dissipate easily due to high hygroscopicity

6.       Weatherability

Silicone resins give excellent results in resistance against UV rays.

7.       Colour retention

Silicones are very useful additives to enhance the gloss and colour protection.

SM prices sharp drop in Europe & Asia

SM on 12th May 2017:

PS on 12th May 2017:

FOB Rotterdam at USD1,020

CFR China at USD1,200

CFR SEA at USD1,060

CFR SEA at USD1,170/MT


On 10th May, Styrene Monomer (SM) prices inched down again. Prices fell mainly of lack buying interest in major markets coupled with a fall in upstream benzene rates.

Benzene prices assessed down at USD700/MT FOB Korea, decline USD10/MT from 9th May. The price falls due to dull demand across the Asian region.


Ample product availability, weaker upstream energy and benzene rates coupled with bearish cues from the Asian SM values, forced sellers to reduce their prices sharply lower across the European & Asian regions. Weak downstream product demand and pricing trends further supported the price fall.
