As winter approaches, heating costs are like an invisible hand, quietly increasing household expenses. You may not realize that cold wind is seeping in from every crack in the window, and the heat in the room is lost bit by bit. Windows are the "black hole" with the largest heat loss, and sealants are the most vulnerable part of the window system. The cold low temperature makes the sealant rigid and brittle, and moisture invades the adhesion interface, accelerating its aging and delamination. At the same time, the window frame and glass produce slight displacements due to different thermal expansion and contraction coefficients. The sealant cannot adapt to these changes, and cracks appear. With cold wind pouring in and warm air escaping, the indoor temperature is difficult to maintain, and the heating cost naturally rises.


To solve this problem, a solution that can truly improve the performance of sealants is needed - IOTA-792 (N-(2-aminoethyl)-3-aminopropyltrimethoxysilane). The silane group of IOTA-792 is hydrolyzed to form silanol, which reacts chemically with the hydroxyl groups on the surface of glass or metal to form a stable covalent bond, firmly locking the substrate. At the same time, its amino functional groups combine with the organic groups in the sealant to enhance the adhesion of the interface. More importantly, the strength of this chemical bond enables it to resist the invasion of moisture and significantly delay the aging and performance degradation of the adhesive layer.

Not only that, IOTA-792 can also optimize the molecular cross-linking structure of the sealant, improving its elasticity and flexibility. Even if the window frame and glass expand or contract due to alternating hot and cold, the sealant can still adhere to the surface of the substrate to prevent cracks. In this way, the window not only restores its sealing performance, but also effectively protects every bit of your warmth in the cold winter, making heating more efficient and economical.
