Froth-Pak Sealant 620 1.75 PCF Spray Foam Kit

Froth-Pak Sealant 620 is a two-component, quick-cure polyurethane foam that can be used to "picture frame" cavities and to fill penetrations and cracks up to 2” thick by 4” wide. Froth-Pak Sealant is a chemically cured foam designed to significantly reduce curing time. It dispenses, expands, and becomes tack-free in seconds, saving pros time on the Jobsite. Froth-Pak Professional Spray Foam continues to bring innovation to the industry with products that helps make buildings and homes more sustainable. All Froth Pak spray foams feature a blowing agent GWP reduction of more than 99% while maintaining the performance attributes professional contractors expect. In addition to the elimination of HFC blowing agents, the new formulation features improved curing time, improved closed cell content and a reduction in overspray via the Insta-Flo Dispenser. This means delivering unsurpassed performance and ease of use while maintaining Froth Pak Spray Foam’s commitments to sustainability.

• 15 ft hose and INSTA-FLO Gun Dispenser & Hose Assembly

• Type: Spray Foam Kit

• Avoid exposing cured foam to temperatures above 240°F
• Tubing inside the tank can become damaged if shaken too hard
• If applied outdoors, be sure to paint or cover foam to prevent discoloration and UV damage
• Always refer to the installation guide for safe usage and local building codes prior to application
• For best results, the tank contents should be at 75°F (24°C) or warmer. Ambient and surface temperatures should be 65°F or above
• The temperature indicator – not available on Froth-Pak 650 kits – on the side of the tank shows the temperature of the contents of the tank, not the ambient air temperature
• Froth-Pak Foam can be applied effectively in cooler air temperatures or on cooler work surfaces provided the kit contents are at least 75°F (24°C). (See user manual, Section 4.3 - Cold weather spray guidance)
• If hoses are not already attached, use the wrench provided in the Gun / Hose Assembly Kit or your own 5/8” wrench to tighten the hose assemblies for both “A” and “B” valves until both are tight
• Apply petroleum jelly to the inside surfaces of the face of the gun
• Do not attempt to reuse the nozzle if the spray has stopped for more than 30 seconds (or more than 15 seconds for the FROTH-PAK High-Density product). Restart times are impacted by temperature. (See section 3.2 in user manual)
• Do not reuse a cured or partially cured nozzle. This may cause foam to crossover in the gun, rendering it unusable
• If A:B ratio appears wrong, check face of the gun to ensure the ports are clear of cured material (you should be able to see the silver finish of the aluminum spool in the ports). Purge foam through gun for a few seconds without a nozzle. Replace nozzle and try again
• To prevent foam from running or dripping from substrate, spray thinner passes
• The foam expands more than the previous formulation, so spray faster passes. Initial spray does not need to be as thick to result in the same desired final thickness
• Apply a flash-coat for optimal adhesion in suboptimal conditions (cool weather, difficult substrates). A fan nozzle is best used for this. Spray a very thin layer (~1/4” thick) on entire surface to be foamed. Allow the foam to become tack free (~1 minute). Then spray as usual to desired thickness

• Protective clothing or impermeable coveralls, including long sleeves (no skin should be exposed)
• Eye Protection, goggles or safety glasses
• Respirator with organic vapor/P100 cartridge
