Formaldehyde Resin

The series product is achromatous and yellowish fat aldehyde hard resin in shape of grain with characteristic of anti-yellowing; it is applicable to the solvent based coating, solvent-based printing ink, and solvent-free industrial coatings, water-based coating, powder coating, resin modification and other related fields. Its performance is able to improve the anti-yellowing of membrane and shorten drying time, enhance membrane hardness, roundness and luster and solid content and reduce VOC discharge, its price is lower than the similar foreign product by 30%, especially the color slurry cost can be reduced by more than 50%, of which its medium and low end products are beyond compare in term of application, its product performance has already reach and surpass that of the similar foreign product.

Be able to dissolve in almost all paint solvents, such as aromatic hydrocarbons, alcohols, ketones, esters, and so on, do not dissolve in water, completely in the non-polar solvents such as mineral oil, aliphatic hydrocarbons, alicyclic hydrocarbon solubility in small.


Polyaldehyde Resin has good compatibility with the resins listed below:

Epoxy resin

urea resin

petroleum resin

Chlorinated polypropylene (CPP)

Cellulose acetate-butyrate

chlorinated PP


vinyl resin

Polyamide resin


vinyl chloride copolymer

phenol formaldehyde resin

Melamine-formaldehyde resin

4.Colorant(general colorant):

YF-A81 has almost universal solubility and compatibility and excellent wetting property, therefore, YF-A81 is applicable to serving as carrier resin of colorant. If it is used with the suitable dispersant, it shall enable the colorant to high tinting strength and reduce the loss during storage to decrease the storage and treatment process for raw material and colorant types and better adapt to the change in paint and pigment market so as to put the paint end product in to market in the shortest possible time. Compared with foreign similar product, its cost can be reduced by more than 30% (regarding the universal colorant YF-A81 resin content, it can be made into 30%-60% liquid based on the different requirement)

5.Colorant content :

In some coatings, higher YF-A81 aldehyde resin content shall adversely affect the adhesiveness or flexibility or weather-ability of the coating. Generally, the content is 5%-15%, the maximum content shall not exceed 20%, if there is special requirement, and the content may be adjusted accordingly, or the 5% in content may be directly used as coating, printing ink, and additive.


  • If it is used for automobile refinishing coatings, it shall improve the luster and hardness and shorten drying time, the addition is 2%-5%.
  • If it is used for alkyd resin, it shall reduce the viscosity and enhance the hardness and luster and improve aridity. To add YF-A81 aldehyde resin of 5%-10% at the final stage in synthesizing process (based on the solid content of alkyd resin);
  • As the modified resin of the amino alkyd baking paint, it shall enhance the hardness and fullness and it may replace the alkyd resin of no more than 20% according to the quality requirement.
  • As the modified resin of the nitro coating, it shall improve the ultraviolet resistance and reduce yellowing, and enhance solid content and luster and tolerance for benzene solvent. Usage: generally, it may replace nitro fiber of about20%-30%.
  • As the modified resin of the alkyd/ chlorinated resin coating, it shall enhance the compatibility between chlorinated resin (especially chlorine ether and chlorinated rubber) and alkyd resin. And improve the luster and solid content. Usage: it may replace the alkyd in the alkyd/chlorinated resin coatings, its dosage shall not exceed 10% of the total resin content.
  • To prepare the hot melt traffic paint (compared with the hot melt traffic paint based on petroleum resin), its base material has better adhesive force. In white types, the titanium white powder quantity may be reduced properly, with better weather-ability. Usage: 1. YF-A81 as base material;2. It can be used with petroleum resin.
It is used in powder coating, and improving leveling property and adhesive force to the base material.Usage: 1. In epoxide powder coating, adopt YF-A81 to replace the reactive resin of 5%-15%;2. Epoxide/polyester powder coating, adopt YF-A81 to replace the reactive resin of 5%-15%;
