Troubleshooting Guide

Common
Problem

Paint build-up on edges

Poor edge coverage

Chemcraft
Solution

Addition of thixotrope

Addition of silicone flow agent

Faster solvent balance

Lower viscosity

Ensure profiles are sanded to remove sharp edges

Common
Problem

Depressions in finish with raised edges and uniform material at center

Undispersed droplets in paint

Chemcraft
Solution

Remove source of contamination

Remove source of incompatibility

Clean substrate before application

Clean equipment before application

Clean air system and ventilation control

Addition of silicone flow agent

Common
Problem

Mottled, blotchy or streaked appearance

Separation and uneven distribution of pigment

Result of Bénard cell formation

Chemcraft
Solution

Increase application viscosity

Lower application thickness

Add thixotrope or thickener

Add dispersant

Add silicone additive to reduce surface tension

Common
Problem

Uniform color change

Surface enrichment of one or more pigments

Different color on disturbed surface/ Rub-up

Chemcraft
Solution

Reduce film thickness

Raise viscosity of coating

Speed drying
