Professionals in construction, renovation, and pipeline maintenance often face frustrating issues such as air and water leaks, as well as poor insulation:

• Gaps around doors and windows let cold air in during winter and cool air out during summer, driving up energy costs.

• Ineffective pipe insulation leads to rapid heat loss and pipe corrosion from condensation.

• Insulation materials crack and degrade in high-temperature environments, losing their thermal protection.

• Rigid gap fillers fail to conform to irregular spaces, resulting in incomplete sealing.

IOTA LSR 3663 liquid foam silicone is the "all-rounder" in insulation and sealing. Once foamed, it tightly fills gaps, insulates, absorbs vibrations, and waterproofs, fully resolving problems like leaks and poor insulation.

The sealing and insulation performance of this foam silicone is exceptional. It expands 2–6 times at room temperature, filling irregular gaps like expanding foam—even tiny cracks around windows and door frames or joints in piping can be tightly sealed to block water and air completely. After curing, it feels like flexible insulation wool: soft, elastic, and highly effective at reducing heat transfer while absorbing vibrations to protect pipes and equipment. Its high-temperature resistance is robust—withstanding up to 300°C—so it won’t degrade or deform even when wrapped around hot pipes, and its flame-retardant properties enhance safety. Light as fluffy willow catkins, it adds no extra weight to structures or pipes.

In insulation, sealing, and construction applications, its performance stands out:

• Pipe insulation sleeves for hot water pipes or industrial high-temperature pipelines minimize heat loss, save energy, and prevent condensation-induced corrosion.

• Gap sealing around doors and windows fills irregular spaces tightly, eliminating drafts to retain warmth in winter and cool air in summer, reducing HVAC energy consumption.

• Equipment insulation layers, such as for high-temperature industrial equipment or oven linings, offer heat resistance, excellent insulation, and vibration absorption.

• Building expansion joint sealing adapts to minor structural movements without loosening, preventing rainwater infiltration.

• Cold storage insulation reduces cold air leakage, maintains low temperatures, and cuts refrigeration costs.

Using it is particularly hassle-free—just keep a few key details in mind:

• Mix Components A and B by weight at 1:1 or 10:1, ensuring thorough stirring for optimal foaming and curing.

• The ideal working temperature is 20°C, where expansion is most stable; lower temperatures may reduce foaming effectiveness.

• Avoid contact with substances like tin, phosphorus, ammonium, or chlorine to prevent product failure; small-scale testing before use is recommended.

• After mixing, there’s a 5–10 minute working window, ample for pouring and filling, and it cures in 20–30 minutes at room temperature—no extra heating or long waits required.

• Store below 25°C—unopened, it lasts up to 1 year. Transport as a standard chemical without special handling. It adapts seamlessly to on-site manual applications or factory-scale production of insulation sleeves.
