SeamKing Pro Hardener
Burn resistant hardener, requiring 3 parts of hardener for 100 parts of resin. Clear hardener will not lighten your color match. This hardener will get your adhesive hard but will not get hot enough when catalyzing to yellow your product. This gives fabricators more freedom to have a range of working time based on how much hardener you put in. Do not add more than 12%.
