Astro Mel™ CR-1

Description

Astro Mel CR-1 is a liquid, partially methylated melamine resin.

Application

Astro Mel CR-1 is a waterborne resin that can be used to crosslink hydroxy-functional polymers in formulations used for wood coatings, nonwoven binders, and textile finishing. This resin also readily self-condenses to provide excellent film hardness. In most cases, Astro Mel CR-1 provides adequate cure response without the addition of a strong acid catalyst. To promote cure at lower temperatures, the use of a blocked acid catalyst is recommended.

Benefits

Astro Mel CR-1 can provide improved solvent, stain, mar, and block resistance to wood coatings and firm, resilient finishes that are highly abrasion and solvent resistant in nonwovens and textile applications. Additionally, Astro Mel CR-1 offers good cure response at temperatures below 150 °C, very low formaldehyde content, and good can stability.
