Top Grif - urethane cold-casting resin for climbing holds


Top Grif HQ consists of low viscosity casting resins that yield virtually bubble-free off-white castings.  
Top Grif is easy to mix and pour, offering the convenience of a 1A:1B  by weight mix ratio. 
Top Grif  readily accepts pigments and fillers (such as Filler K-5, Geba or Rondofil from Samson Kamnik).
Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Top Grif HQ include reproducing small to medium size sculptures, production of climbing holds, making prototype models, special effect props, decorative jewelry and taxidermy (bones, antlers, teeth).
