MELCROSS85

High Imino Type Benzoguanamine Resin

MELCROSS 85 is a low methylol content and high imino functionality benzoguanamine type.

This resin is a very effective crosslinking agent for backbone polymers containing hydroxyl,  carboxyl  or amide functional groups such as epoxy, alkyd/polyester or acrylic resins.

MELCROSS-83 resin is insoluble in water. Due to its hydrophobic nature, this resin has to be dissolved initially in the organic phase of the water reducible backbone polymers.

This resin is a very efficient crosslinking agent for polymers containing carboxyl, hydroxyl or amide groups, such as epoxy, alkyd and acrylic resins.  MELCROSS-85 crosslinking agent was developed primarily for electro-coating primers requiring high corrosion and detergent resistance.

And has a properties of improved salt-spray resistance, good adhesion to metal surfaces.

MELCROSS-85 resin is supplied 80% solution in 2-Butoxy ethanol viscous resins.

Introduction

MELCOSS-85 resin is suitable for a can coating and electro coating primers purpose.
Designed for Can coating with polyester and epoxy resin in high viscosity type paints.
Methylated high Imino type Benzoguanamine resin gives Detergent resistance, Improved salt-spray resistance, Adhesion properties to metal surfaces.
The compatibility with alkyd resins, polyester resins, acrylic resins and epoxy resins is very good.
Storage stability at room temperatures is minimum one year after delivery. 
To control the stability, you can use primary alcohols,  amins or with combination of these for neutralization and PH adjustment.
Electrocoating paints containing MELCOSS-85 crosslinking agent have higher throwing power than comparable systems and this resin can be used in the preparation of a  wide range of general purpose industrial finishes.
