A chemical grout will result from mixing the following components at a 1:1 ratio:
| Component A | Component B |
| TYTRO AC-300 | Water |
| Water | SP-200 |
| TE-300 |
Environmental Conditions
Precautions
TYTRO™ AC-300 Grout is used with SP-200 (sodium persulfate) and TE-300 (triethanolamine).
Workers handling the grout must wear rubber gloves, goggles, and waterproof shoes. If the grout comes in contact with the skin, it should be washed off immediately, with water. Avoid breathing of the grout vapor.
- Do not let SP-200 and TE-300 come into contact with each other prior to field mixing. The reaction is exothermic (heat producing) and may cause fire.
- Store SP-200 and TE-300 separated from each other, at 40⁰ F-80⁰ F.
- TE-300 and SP-200 are incompatible with aluminum. Do not use aluminum equipment in the presence of TE-300 and SP-200.
- Prolonged exposure to UV, sunlight, and elevated temperatures above 85ºF will cause solidification of the product
Limitations
This product is not intended to fill large void spaces.
Storage & Handling
Store TYTRO™ AC-300 at 40⁰ F-80⁰ F.
Store SP-200 and TE-300 separated from each other, at 40⁰ F-80⁰ F.
