Multipurpose DIY Epoxy Resin
Description
Technical Parameters
Top Multipurpose DIY Epoxy Resin Manufacturer
DIY-Friendly Formula: A 1:1 equal-ratio mixing design eliminates the need for precise weighing, making it easy for beginners. Its low viscosity facilitates pouring into small molds, and the curing process generates no significant heat, preventing material deformation.
High Creative Compatibility: Compatible with various DIY materials such as dried flowers, seashells, and pigments. It does not chemically react with pigments or glitter, allowing for precise rendering of creative effects. Light transmittance exceeds 88%.
Environmentally Friendly and Safe: Complies with RoHS environmental standards. Low odor and low irritation before curing; non-toxic and odorless after curing. Suitable for making personal accessories and home decorations.
Balanced Practical Performance: Shore hardness ≥80D, wear-resistant, scratch-resistant, waterproof, and moisture-proof. Resistant to everyday stains after curing, making it suitable for long-term use in practical products such as tabletops and coasters.

How Multipurpose DIY Epoxy Resin works?
Xinshan is a professional resin manufacturer!
Proportional Polymerization
After mixing components A and B in a 1:1 ratio, the epoxy groups and the active ingredients of the curing agent rapidly combine to form a three-dimensional network structure, balancing hardness and toughness to meet the performance requirements of DIY scenarios.
Mild Curing Control
Initial setting occurs in 4-6 hours at room temperature (20-25℃), and complete curing occurs in 24 hours. The low exothermic formula (peak temperature ≤50℃) protects heat-sensitive DIY materials (such as dried flowers and polymer clay).
Material Impregnation and Coating
The low-viscosity adhesive fully impregnates the surface and crevices of the material, forming a tight coating layer after curing to prevent fading of dried flowers and oxidation of metals, improving the durability of the finished product.
Surface Film Formation Mechanism
During the curing process, molecules align in a specific direction, forming a dense surface film that reduces moisture and oxygen penetration, giving the finished product waterproof and stain-resistant properties, facilitating daily cleaning.
FAQ
1. Is the mixing time sufficient for complex DIY projects?
The mixing time is approximately 40-60 minutes at 20-25℃, allowing for ample time to complete complex processes such as mold pouring and jewelry assembly. It is recommended to mix only the required amount at once to avoid wasting excess adhesive after curing.
2. Will mixing with acrylic paint affect transparency or curing results?
Completely compatible. It is recommended that the amount of paint added not exceed 5%, as excessive amounts may reduce transparency. Mixing does not affect the curing speed; the finished product has a uniform and stable color without layering.
3. Will the jewelry I make cause discomfort for people with sensitive skin?
Completely non-toxic and odorless after curing, meeting skin contact safety standards, and will not irritate sensitive skin. It is recommended to wear the finished product only after it has fully cured to avoid any uncured residue.
4. Will the curing speed be affected by low temperatures in winter?
It will be slightly longer. Complete curing at 10-15℃ requires 36-48 hours. Curing can be accelerated using heating or a heat lamp (keeping the temperature below 30℃) to avoid high temperatures causing bubbles.
5. How to avoid air bubbles on the surface of the finished product?
Stir slowly along the container wall during mixing to reduce air intake; after pouring, quickly sweep the surface with a lighter to remove bubbles, or place it in a vacuum chamber for degassing (suitable for batch production).
6. How to store unused resin, and how long can it be stored?
Separately seal components A and B, and store in a cool, dry place at 10-30℃, avoiding direct sunlight; unopened, it has a shelf life of 18 months. Once opened, it is recommended to use it within 3 months. Clean the bottle opening after each use to avoid contamination.
