Temperatures below 75° F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75° to 80° F or above. Accurate measuring of these products is extremely critical. Working time before foaming: approx. 45 seconds Time before full expansion: approx. 5 minutes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBH4XQ9P | | Brand | Fiberglass Supply Depot | | Brand Name | Fiberglass Supply Depot | | Colour | Clear | | Compatible Material | Vinyl | | Container Type | Can | | Country of Publication | USA | | Customer Reviews | 4.4 out of 5 stars 181 Reviews | | Full Cure Time | 5 Minutes | | Global Trade Identification Number | 00819794023221 | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Weight | 2.72 kg | | Manufacturer | Fiberglass Supply Depot Inc. | | Manufacturer Part Number | FBACPOLY6LBGK | | Material | Resin | | Material Type | Resin | | Model | FBACPOLY6LBGK | | Number of Pieces | 2 | | Other Special Features of the Product | Soundproofing, Insulation, Buoyancy | | Special Feature | Soundproofing, Insulation, Buoyancy | | Specific Uses For Product | Boats, Dock Flotation, Soundproofing, Filling Voids, Insulation | | Viscosity Level | Low | | Volume | 128 Fluid Ounces | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Fiberglass Supply Depot - **Item Form:** Liquid - **Material:** Resin - **Special Feature:** Soundproofing, Insulation, Buoyancy - **Specific Uses For Product:** Boats, Dock Flotation, Soundproofing, Filling Voids, Insulation ## Images ![6 Lb.
