1. Product Overview

Deep Pour Epoxy Resin is a two-component, 100% solids, low-exotherm epoxy system specifically formulated for thick-layer casting applications. It is designed to allow single pours of 2-4 inches (5-10 cm) without overheating, cracking, or yellowing, making it ideal for artistic projects such as river tables, wood fillers, craft castings, and deep mold creations. The product features ultra-low viscosity, excellent self-leveling and self-degassing properties, curing to a crystal-clear, high-gloss finish with exceptional durability and UV resistance, suitable for both professional and hobbyist use.

3. Technical Parameters

3.1 Mixing Parameters

• Mix Ratio: Common ratios include 2:1 (weight/volume ratio, Part A: Part B) and 3:1 (volume ratio, Part A: Part B); some models adopt 100:28 (weight ratio, Part A: Part B)
• Mixing Method: Stir Part A thoroughly to avoid sedimentation, then add Part B slowly while stirring continuously with a power drill or manual stirrer for 3-5 minutes until the mixture is uniform, bubble-free, and consistent in texture. Ensure both components are at room temperature (21℃ minimum) before mixing
• Pot Life (Working Time): 90 minutes at 25℃ (for standard mixes); 5.5 hours at 25℃ for 150g mass (varies by formulation and mix volume) – larger mix volumes shorten pot life due to exothermic reaction
• Application Time: Complete pouring and shaping within the pot life to ensure optimal flow and avoid premature curing

3.2 Physical Properties (Mixed State, 25℃)

• Density: Part A: 9.3 lbs/gal (1.11 kg/L); Part B: 7.9 lbs/gal (0.95 kg/L); Cured density: 1.15 g/cm³ (0.040 lbs/in³) ASTM D792
• Viscosity: Part A: 1000 cp (mPa·s); Part B: 10 cp (mPa·s); Initial mixed viscosity: 260 cp (mPa·s) ASTM D2196 – ultra-low viscosity ensures excellent flow and bubble release
• Pouring Depth: Maximum single pour depth: 2-4 inches (5-10 cm); Safe pour depth: 1.2 inches (3 cm) if temperature control is not optimal; no layering required for thick pours
• Self-Leveling & Defoaming: Excellent self-leveling property for a smooth, even finish; self-degassing formula minimizes bubbles, with optional assistance from a defoaming roller for perfect results

3.3 Curing Parameters

• Touch-Dry Time: 4-6 hours at 25℃
• Walkable Time: 24-48 hours at 25℃ (varies by temperature and mix volume)
• Full Curing Time: 72-96 hours at 25℃; reaches maximum hardness and performance after full curing; post-curing can slightly improve heat resistance (HDT increases from 118°F to 122°F) ASTM D648
• Curing Temperature Range: 16-25℃ (optimal: 20-25℃); substrate temperature must be above the dew point to avoid moisture condensation affecting adhesion; low temperatures extend curing time, while high temperatures accelerate reaction and increase exotherm
• Exothermic Control: Ultra-low exothermic reaction to prevent overheating and deformation during thick pours – critical for avoiding cracking in deep castings

4. Performance Parameters

4.1 Mechanical Performance

• Hardness (Shore D): 82 (ASTM D2240) – high hardness for excellent scratch resistance
• Tensile Strength: 8,100 psi (ASTM D638); Tensile Elongation: 4.3% (ASTM D638)
• Flexural Strength: 13,480 psi (ASTM D790); Flexural Modulus: 438,423 psi (ASTM D790)
• Compressive Strength: 11,260 psi (ASTM D695)
• Impact Resistance (Notched Izod): 0.84 ft-lb/in (ASTM D256) – good toughness to prevent brittleness after curing
• Volumetric Shrinkage: 3.85% (ASTM D792/D2196) – minimal shrinkage to ensure dimensional stability in castings

4.2 Chemical & Environmental Resistance

• Chemical Resistance: Resistant to household detergents, oils, grease, weak acids, and alkalis; compatible with food contact (food-safe) when fully cured
• UV Resistance: Excellent, prevents yellowing and discoloration under long-term sunlight exposure, maintaining crystal clarity for extended periods
• Heat Resistance: Heat-resistant up to 93℃ (200°F); post-curing can enhance heat resistance slightly
• Water Resistance: Excellent, waterproof and moisture-tolerant after full curing, suitable for indoor and covered outdoor applications

5. Application Parameters

5.1 Applicable Substrates

Suitable for various substrates including wood, metal, stone, ceramics, and plastic; ideal for river tables, bar tops, table tops, flower preservations, deep molds, and artistic crafts – designed specifically for thick casting applications

5.2 Surface Preparation Requirements

• All substrates must be clean, dry, and free of dust, oil, moisture, sap, lint, and sanding debris to ensure optimal adhesion
• Wood substrates: Ensure moisture content ≤10% to prevent bubbling; seal porous wood with a thin layer of epoxy if needed to avoid air entrapment
• Substrate temperature must be 3-5℃ above the dew point to avoid moisture-related issues during curing

5.3 Application Methods

• Tools: Mixing containers, power drill with mixing attachment, pouring jug, spreader (if needed), defoaming roller
• Application Thickness: Single pour: 2-4 inches (5-10 cm); multiple pours can be done after full curing of the previous layer for thicker applications
• Application Environment: Relative humidity ≤70%, temperature 16-25℃, dust-free, and well-ventilated; avoid direct sunlight and strong wind during pouring and curing
• Post-Application Care: Keep the application area clean during curing to prevent dust or impurities from adhering to the uncured surface

6. Storage and Handling

• Storage: Store in a sealed, light-proof container in a cool, dry, well-ventilated warehouse (16-25℃); keep away from direct sunlight, open flames, and heat sources; store Part A and Part B separately to avoid accidental mixing; unopened shelf life is 12 months, 6 months once opened
• Handling: Wear protective gloves, goggles, and masks during mixing and application; ensure good ventilation; in case of contact with skin or eyes, rinse immediately with plenty of water for 15 minutes and seek medical advice if necessary; avoid ingestion or inhalation
• Waste Disposal: Dispose of unused mixture and packaging in accordance with local environmental protection regulations; do not pour into sewers or soil
