Nelson Firestops - MSDS
Nelson Firestop Sealant (CLK™) is a family of one part silicone flexible sealants, used to protect from the spread of fire, smoke, gases and water. It is designed for applications of through stop penetrations and in construction joints. It is offered in two forms, a non-sag caulk which can be troweled and a self-leveling grade suited for floor applications.
Nelson Compound (CMP™) is a cementitious material that is mixed with water. It is similar in appearance to mortar and can be troweled to a smooth finish that provides a weather resistant, non-shrinking fire-rated seal.
Nelson Composite Sheet (CPS™) is a rigid, elastomeric, fire resistant panel used to seal penetrations and maintain the rating of fire rated floors or walls. It consists of a rigid panel, primarily composed of a 5/16” thick elastomeric sheet, bonded to a 28 gauge galvanized steel sheet on one side. The composite sheet is reinforced with hexagonal shaped steel wire mesh and bonded with .003" aluminum foil on the back side.
Nelson Firestop Elastomeric Sealant (ES1399™) is a cost effective, water based acrylic latex, endothermic, fire protective sealant. It is designed for applications of through firestop penetrations and in construction joints.
Nelson Firestop Fire Protective Cable Coating (FSC™) is water based, intumescent, fire protective coating designed to enhance the fire resistance of electrical power, communications and control cables. It is commonly applied to continuous cable runs to prevent the propagation of fire. It is designed for labor saving spray applications on cables.
Nelson Firestop Joint Coating (FSC3™) is a water based acrylic latex, elastomeric, fire protective coating for use on construction joints. It is designed for labor saving spray applications onto construction joints and perimeter joint systems (curtain wall assemblies).
Nelson Firestop Putty (FSP™) is a completely premixed and ready-to-use formula that can be hand pressed into place forming an immediate fire seal. When exposed to fire the intumescent material expands to seal voids created from fire exposure on deteriorating penetrating items. FSP™ is a blend of organic and inorganic materials that is hand moldable. FSP™ is reusable when adding or changing penetrating items since the material remains pliable and does not set up.
Nelson Firestop Sealant (LBS3™) is an elastomeric, water based, intumescent, fire protective sealant. It is designed for applications of through firestop penetrations and construction joints. It is used to seal against the spread of fire, smoke, gasses and water.
Nelson Firestop Mineral Wool is used in many Firestop Systems in conjunction with various Firestop Sealants to assure the integrity of the fire rated seal against the spread of fire, smoke and gasses. The Mineral Wool offered is a packing grade wool designed for hand packing.
Nelson Fire Brick is a soft, pliable, intumescent material that is ideal for applications where the Firestop application may be required to be re-penetrated. Upon the event of a fire, the brick material expands within the opening, forming a solid char that prevents through penetration of the fire.
Nelson pipe choke system (PCS™) is a prefabricated device used to seal penetrations and maintain the rating of fire rated floors and walls. The pipe choke is designed for penetrations of non-metallic pipes. When exposed to fire, the intumescent material expands to seal voids created from fire exposure on deteriorating penetrating items. The PCS™ consists of a heavy gauge metallic collar filled with a highly intumescent, pliable material.
Nelson Firestop Pillow (PLW™) is a compressible firestop device that is well suited for installations where frequent changes may be required. PLW™ consists of a mineral fiber treated with a highly intumescent material enclosed in a strong polyethylene bag. When exposed to fire, the pillows expand to lock the seal in place. Even though PLW™ is classified as a permanent firestop system for several applications including steel and aluminum cable trays, PLW™ also is an excellent temporary seal. ¾
Nelson Wrap Strip (WRS3™) is a highly intumescent firestop wrap system. When exposed to fire, the wrap strip expands and forms a hard char to seal off the penetrating item and preventing the passage of fire and hot gasses.
