SciGrip SG5000 Black Mold Repair Compound Rapid-Cure 1:1 MMA Methacrylate Adhesive

Product Name

- SciGrip SG5000 Black Mold Repair Compound Rapid-Cure 1:1 MMA Methacrylate Adhesive

Brief Description

- SciGrip SG5000 is a high-strength, two-component, 1:1 mix ratio methyl methacrylate (MMA) adhesive engineered for rapid curing and durable structural bonding. It is particularly effective for repairing fiberglass molds and for joining a wide array of metals, plastics, and composites.- This adhesive is known for its fast work and fixture times, excellent chemical resistance, and ability to bond with minimal surface preparation.

Popular Applications & Uses

- Repairing cracks and dings in fiberglass molds.- Structural bonding of metals such as aluminum, carbon steel, stainless steel, and coated metals.- Bonding various plastics including ABS, acrylics, polycarbonates, and PVC.- Adhering composites like fiberglass, epoxy, polyester/DCPD, vinyl ester, and gelcoats.- Assembly of components in transportation (e.g., motorhomes, trucks, rail, automotive panels).- Marine applications, including boat building and bonding composite materials.- General industrial assembly and fabrication requiring strong, fast bonds.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Construction/Building Services- General Manufacturing- Industrial Supply- Marine- Metal Fabrication- Mold Making/Casting- Plastic Fabrication- Sign & Display- Transportation/Specialty Vehicle

Special and Unique Features

- Rapid-cure formulation allows for quick assembly and reduced production times.- Primerless metal bonding for most metals, eliminating surface treatment steps.- Non-sag formula, ideal for vertical or uneven surface applications.- Excellent environmental and chemical resistance, ensuring durable bonds in harsh conditions.- High impact, fatigue, and shock load resistance.- Convenient 1:1 mix ratio for consistent results with manual or metered mixing systems.- GREENGUARD certified for low chemical emissions.

Key Properties

- **Type:** Methacrylate (MMA) Adhesive- **Mix Ratio:** 1:1 by volume and weight- **Color:** Black (also available in Amber)- **Working Time:** Varies by specific SG5000 variant (e.g., 5-8 minutes for SG5000-06, 2-5 minutes for SG5000-03)- **Fixture Time:** Varies by specific SG5000 variant (e.g., 10-12 minutes for SG5000-06, 6-8 minutes for SG5000-03)- **Tensile Strength:** 5,000 - 5,800 psi (35 - 40 MPa)- **Lap Shear Strength:** >2,600 psi (18 MPa)- **Maximum Tensile Elongation:** >5%- **Gap Fill:** 0.02 - 0.5 inches (0.50 - 12.7 mm)- **Service Temperatures:** -40 to 212°F (-40 to 100°C)

Surface Compatibility

Known backups / known substitutes

- Other products within the SCIGRIP SG5000 series with different working times (e.g., SG5000-03, SG5000-06, SG5000-13).- Other SCIGRIP and Weld-On brand adhesives, particularly other MMA structural adhesives.- General MMA adhesives from other manufacturers, such as Infinity Bond MMA 422 (for slower set, high strength applications).- Epoxies and polyurethanes, though MMA adhesives often offer advantages in cure speed and surface preparation.

Comparison Note

- SciGrip SG5000, as an MMA adhesive, stands out from traditional epoxies and polyurethanes due to its rapid curing at room temperature, significantly reducing assembly times.- It provides exceptional bond strength to a wide range of dissimilar materials, including metals, plastics, and composites, often requiring minimal surface preparation.- Its toughened flexibility allows it to accommodate thermal expansion and contraction, while offering superior impact, fatigue, and chemical resistance, making it suitable for demanding structural applications.
