Description
Dibenzoyl peroxide-based reactive agent in the form of white powder used to induce curing of all PMMA based (ALSAN RS and ALSAN CIVIL) resins during membrane application.
ITEMS PER SKID:
Depends on weight:
0.1 kg - 6000
25 kg - 24
Material Use:
ALSAN RS CATALYST POWDER is a reactive curing agent specifically formulated for use with all ALSAN RS resin-based products. It is essential in initiating the polymerization process during the application of ALSAN RS membranes and coatings, ensuring proper curing and performance of the resin system.
System Components:
ALSAN RS CATALYST POWDER is not a standalone product but a required component in the ALSAN RS liquid-applied membrane system. It is used in conjunction with various ALSAN RS resins, including base coats, topcoats, and detailing resins. The catalyst must be mixed with the resin component prior to application to activate the curing process. The system typically includes:
- ALSAN RS resin (base coat or topcoat)
- ALSAN RS CATALYST POWDER
- Reinforcement fleece (where applicable)
- ALSAN RS primers (depending on substrate)
Applications:
This catalyst is used in roofing, balconies, and other waterproofing or surfacing applications where ALSAN RS resin systems are specified. It is suitable for both horizontal and vertical surfaces and is commonly used in high-performance waterproofing and surfacing systems requiring rapid cure and durability.
Application Details:
Before use, the entire container of ALSAN RS resin must be mixed thoroughly for two minutes using a slow-speed mechanical agitator (200–400 rpm). The catalyst is then added in a pre-measured amount based on the resin type, weight, and ambient temperature. A 15 ml measuring spoon corresponds to 0.01 kg of catalyst. After adding the catalyst, the mixture must be stirred for an additional two minutes before application. Only catalyze the amount of resin that can be applied within 10–15 minutes, as this is the pot life of the catalyzed resin. The exact catalyst dosage and working time depend on environmental conditions and resin type, so refer to the specific resin TDS for detailed instructions.
Special Notes:
- ALSAN RS CATALYST POWDER is highly reactive and must be stored properly to avoid fire hazards. It should be kept in a cool, dry, and well-ventilated area, away from direct sunlight and ignition sources.
- The product must not be stored at temperatures exceeding 30 °C (86 °F).
- Avoid contact with rust, iron, and copper, which can trigger decomposition.
- Shelf life is six months in unopened original packaging.
- This catalyst is essential for the curing of ALSAN RS resins and cannot be substituted.
- Always consult the specific ALSAN RS resin TDS and your SOPREMA representative for precise catalyst ratios and application conditions.
Limitations and Environmental Conditions:
- Pot Life: 10–15 minutes after mixing with resin
- Temperature Range for Use: Follow resin-specific guidelines; catalyst amount varies with temperature
- Storage Temperature Limit: Do not exceed 30 °C (86 °F)
- UV Stability: Not applicable to catalyst; UV stability depends on the resin used
- Coverage: Not applicable; dosage is based on resin weight and temperature
ALSAN RS CATALYST POWDER is a critical component in the ALSAN RS system and must be used precisely as directed to ensure proper curing and performance of the waterproofing or surfacing system.
