Adhesive Resin AN220 - Adhesion Promoter
AN220 is a modified resorcinol-formaldehyde resin, which is a methylene acceptor in resorcinol-formaldehyde-silica adhesion system. It is used in combination with a methylene donor to effectively bond the rubber to various framework materials. Compared to resorcinol, it will reduce fuming and weight loss during compounding.

- 2. （2）.Store in a cool and dry warehouse to avoid moisture absorption and agglomeration.
- 3. The product has a shelf life of 24 months from the date of manufacture.
Applications
Applications
1. AN220 can be used as an adhesive to enhance bond of synthetic fibers or plated wire steel to rubber for tires, conveyer belt, drive belt, damping rubber, anti-vibration rubber and industrial component, etc.
2. AN220 is used as methylene acceptor in resorcinol-formaldehyde-silica adhesion system and it is often used with methylene donors, such as hexa-methylenetetramine (HMTA) or hexamethoxymethylmelamine (HMMM).
3. The amount of AN220 in the compounding system is recommended to be 1-3parts, and the amount of the methylene donor is recommended to be 1-3 parts.
4. The fuming is significant reduces during processing, it also has excellent adhesion and adhesion retention.
