Why are there two types of HIT-HY 200?

Dear Customer,

thank you for reaching out to us. Hilti HIT-HY 200 adhesive is available in two options, Hilti HIT-HY 200-A, and Hilti HIT-HY 200-R. Both options utilize the same technical data so there is no need to include the “A” or “R” in the product specification or the General Structural Notes. Hilti HIT-HY 200-A will have shorter working times and curing times than Hilti HIT-HY 200-R. The user can select product gel time suitability based on temperature of the base material and jobsite time requirements. The packaging for each is different which helps the user distinguish between the two adhesives. I hope I have answered your question. If there is anything else, please let me know.

All the best,
Elizabeth
