Pecora 895NST Structural Silicone Glazing & Weatherproofing Sealant, Aluminum Stone, 20oz Sausage

Pecora PEC-895-515S Structural Silicone Glazing & Weatherproofing Sealant, Aluminum Stone, 20oz Sausage

Pecora 895NST is a high-performing, neutral curing, medium modulus silicone sealant specifically designed for structural and non-structural glazing, with excellent aesthetic characteristics in that it will not stain sensitive porous natural stones such as granite or marble and will not contribute to residue run down on nonporous surfaces such as metal or glass curtain wall facades. Reduction in long term dirt pick up on sealant surface is also a feature of the Pecora NST line of silicone architectural grade sealants. With a dynamic movement capability of ±50% to complement its structural strength, 895NST is equally efficient as a weatherseal in the vast majority of sealant ap plications other than glazing.
