Room or ambient temperature curing systems offer easy processing and high reliability. These one and two component systems are used in bonding, sealing, coating and potting/encapsulation applications.
Reaction Curing Compounds
Many two component epoxy systems will polymerize at ambient temperatures when the epoxy resin reacts with a hardener. After curing is initiated an exothermic reaction occurs. Set up times range from 4-8 minutes at ambient temperatures to 24 to 48 hours. Their rate of cure will depend on bond line thickness, humidity, temperature and the types of substrates they are joining.
- Two component epoxies
Addition Cured Systems
Room temperature vulcanizing (RTV) silicones cure at room temperature when the base component is mixed with a catalyst. Addition cured system do not require exposure to air for cross-linking. No by-products are released during cure. They can cure in closed environments. These systems feature outstanding flexibility combined with high temperature resistance.
- Two component silicones
Water Evaporation Curing
One part, no mix water based adhesive systems feature convenient cure schedules and simple dispensing. These ecologically safe, non-toxic, non-flammable formulations bond well to many substrates. Products offer good setting characteristics, spread smoothly and are odorless. These cost effective compounds can be diluted with water and can cure more rapidly upon exposure to heat.
- Latex systems
- Silicate based systems
Moisture Curing Adhesive Systems
Master Bond ready-to-use one component moisture curing adhesives feature easy application. They reduce manufacturing costs, bond well to many similar/dissimilar substrates and are serviceable over a wide temperature range. These compounds alleviate pot life concerns and eliminate waste. They provide consistent, reliable performance and are employed in the assembly of many industrial products.
- One part silicones
- Cyanoacrylates
