Amino resin H70A
Product Description:
H70A resin is a high methylol methyl ether melamine-formaldehyde resin with moderate alkylation, high methylol content and low imino functionality. H70A resin is partially soluble in water and has excellent compatibility with water-soluble main chain polymers, which makes H70A resin suitable for a variety of water-based industrial baking paints. It can be crosslinked with hydroxyl and amide-based polyester resins under the catalysis of weak acids to make water-based or solsol-based baking paints, such as general metal baking paints, color board paints and furniture varnishes. However, the polyester resin containing carboxyl functional group is not easy to crosslink with "H70A" resin.
Advantages:
1. High hydroxymethyl content
2. Weak acid catalysis
3. Good reaction activity
4. Hardness and flexibility balance is very good
5. Fast catalytic curing reaction
6. Excellent catalytic stability
Solubility:
1. White solvent oil: limited dissolution
2. Xylene: partially dissolved
3. Methyl ethyl ketone: completely dissolved
4. Butanol: Completely dissolved
5. Water-soluble resin: partially dissolved
Compatibility:
- Long oil alkyd resin: insoluble
- Medium oil alkyd resin: completely soluble
- Short oil alkyd resin: completely soluble
