(Environmentally friendly) formaldehyde resin KC-81
Overview: This series product is a colorless to yellowish anti-yellowing aliphatic aldehydes hard resin, granule-like appearance. Applicable to solvent-based coatings, solvent-based ink, solvent-based coatings, waterborne coatings, powder coatings, a variety of resin-modified, and other areas. Its performance improved yellowing resistance film and shorten the drying time and improve the solid content to reduce VOC emissions, the price of similar foreign products offer more than 30%, in particular, is a universal colorants costs can be reduced by 50% or more of its middle and low solvent adaptation similar foreign products can not be with Bimei, product performance has reached and more than similar foreign products.

Excellent anti-yellowing


Pigment paste (Universal colorants):
KC-81 has almost universal solubility and compatibility, and has excellent pigment wetting. For this reason, so that KC-81 is very suitable as a carrier resin, pigment paste. With the appropriate dispersant can paste used in conjunction with a very high color strength and to reduce the loss in the storage process, reduce the inventory of raw materials and paste varieties and processing. Changes in paint pigments to enhance market resilience, in the shortest possible time to paint finished products into the market, compared with the cost of similar foreign products can be reduced by 30% or more. (Universal colorants KC-81 resin containing the amount of content according to different requirements could be made of 30% -60% of the liquid).

Note if they are ignoring the consequences of
Paste itself • KC-81 and the compatibility between dispersant
• solvents and compatibility between dispersant
• pigments and compatibility between dispersant
• KC-81 content of
• The amount of dispersant • scattered poor poor mobility, poor stability
• dispersed bad, poor mobility, poor stability
• dispersed bad, poor mobility, poor stability
• or affect the coating performance, or color operation
• or affect the stability, or affect the coating performance
• Stability • paint itself affect the performance of pigment paste, there irritant effect crystal, floating phenomena such as color and Flooding
Colorants and coatings • between the phase between the two adaptive
Paste is mainly dispersed in the coating agent and the solvent and resin compatibility • In the process of adding color paste, there irritant effect crystal, floating phenomena such as color and Flooding


Content of the paint:
In some coatings, KC-81 high levels of formaldehyde resin will affect the paint adhesion or flexibility, or weatherability. The general content of 5% -15%, the maximum shall not exceed 20%, if there are special requirements, you can self-regulate. 5% can also be used directly as coating, ink additive.
