Advanced Material Lab Testing for Every Stage of Development

At Resin Formulators, we offer a comprehensive suite of services that empower engineers and manufacturers to make informed, intelligent decisions. From mechanical, dynamical, and thermal characterization capabilities to custom epoxy formulations, we provide the tools and expertise needed to optimize performance, ensure quality, and validate material properties for continued use—all while delivering exceptional value.

From R&D to quality assurance, our materials characterization services are designed to meet demanding aerospace and other advanced manufacturing industry standards. Conducted in our world-class laboratory in Carson, CA, our in-house testing services are performed by our expert chemist on-site. By streamlining the testing process, we help engineers speed up the product development process, saving both valuable time and money.

Here’s how we help you get the most out of your materials:

• Compression Strength Testing: Understand the stress levels at which materials experience plastic deformation to ensure durability and performance.
• Coefficient of Thermal Expansion (CTE): Determine how materials respond to thermal changes using thermomechanical analysis.
• Degree of Cure Analysis: Measure the transition of thermoset resins from flowing liquid to solid matrix, providing insights into mechanical strength and material stability.
• Density (Specific Gravity): Accurately measure mass-to-volume ratios, eliminating temperature variations for consistent results.
• Differential Scanning Calorimetry (DSC): Identify material transitions and thermal properties through precise temperature and heat flow measurements.

Our capabilities extend beyond standard testing to offer specialized services that address the unique challenges of thermoset materials:

• Dynamic Mechanical Analysis (DMA): Evaluate materials' responses to stress, temperature, and frequency for a deeper understanding of engineering limitations.
• Glass Transition Temperature (Tg): Analyze thermal characteristics to determine the temperature range for optimal material performance.
• Lap Shear Strength: Assess the strength of bonded joints under tensile forces to improve adhesive formulations.
• Water Absorption Testing: Measure moisture resistance to ensure long-term material reliability in challenging environments.
• Elongation & Tensile Strength: Determine material flexibility and stress resistance at the point of failure.
• Fourier Transform Infrared Spectroscopy (FTIR): Analyze the absorption, emission, and photoconductivity of materials for a detailed chemical fingerprint.

We’re committed to delivering a full suite of testing services, enabling our customers to confidently develop materials that meet their unique needs. Additional test offerings include:

• Gel Time: Define the duration required for a resin system to gel and become highly viscous.
• Heat Capacity: Measure the amount of heat required to raise a substance’s temperature by 1°C.
• Heat of Reaction & Cure Kinetics: Evaluate the exothermic behavior of thermally reactive materials for enhanced product development.
• Melting Point: Assess material purity by identifying the temperature at which it transitions from solid to liquid.
• Mixed Viscosity: Measure the resistance to flow of a catalyzed resin system at 75°F.
• Modulus (Resin Characterization): Determine the relationship between stress and deformation within a material's elastic limit.
• Pot Life: Measure the workable time of a mixed resin system before its viscosity doubles.
• Shore Hardness (00, A, D): Assess surface resistance, abrasion resistance, and durability using durometer testing.
• Sub Ambient and Elevated Lap Shear Testing: Evaluate tensile lap shear strength under extreme temperature conditions (-200°F to 600°F).
• T-Peel Strength: Measure the relative peel resistance of adhesive bonds between flexible adherends.
• Viscosity Testing: Evaluate flow resistance under ambient, elevated, and curing conditions for optimal process development.
