SCIGRIP 4 is a water-thin, somewhat flammable cement formulated to quickly develop very clear and high strength bonds for many thermoplastic substrates. The bond is achieved by first softening the surfaces to be joined and then fusing them together with the dissipation of the solvent. The initial bond forms within a matter of minutes and is followed by a significant and continual increase in bond strength over the next several hours. SCIGRIP 4 may be preferred by some plastic fabricators because it is less likely to leave white marks (commonly called blushing). For similar applications but faster setting cement, SCIGRIP 3 is recommended. This product is not for general consumer use. It is an industrial product intended for use by industry.

• CRYSTAL CLEAR BOND — Specially formulated solvent cement creates virtually invisible joints in acrylic, achieving clarity that preserves 92% light transmission for flawless display and optical applications. Temperature rated from -40°F to 180°F with 8,000 PSI tensile strength. DCM and TCE free formula meets modern safety standards without sacrificing performance.
• PINT SIZE — One pint (16 fl oz) of professional-grade Weld-On #4 acrylic solvent cement. Low-viscosity water-thin formula wicks into joints via capillary action for seamless, gap-free bonds. Ideal for production runs and large fabrication projects requiring consistent, repeatable results across multiple assemblies.
• MULTI-INDUSTRY APPLICATIONS — Purpose-built for acrylic fabrication, retail display cases, point-of-purchase signage, museum exhibits, aquariums, laser-cut assemblies, and CNC-machined acrylic components. Produces optically clear joints that disappear into the substrate — critical for professional display, architectural glazing, and commercial signage projects.
• EASY PROFESSIONAL FABRICATION — Apply with needle applicator bottle using capillary action along pre-fitted joints. Compatible with cast and extruded acrylic sheet. Bonds cure to handling strength quickly, allowing efficient workflow in shop environments. No mixing required — ready to use straight from container for consistent, repeatable professional-grade acrylic assembly.
• PRECISION TOLERANCES & QUALITY — Dimensions held to +/- 0.010" ensuring consistent, precise fit for fabrication and engineering applications. Manufactured under ISO 9001:2015 certified quality management standards for reliable material quality on every order.
