Resin Course

Lesson 1 • Personal Protective Equipment

Covers glove types, respirator selection, eye protection, and protective clothing for resin environments. Ensures students choose PPE matched to specific resin hazards.

Lesson 2 • Tools, Equipment, and Workspace Layout

Covers mixing vessels, scales, dispensers, heat guns, and mold-release tools. Proper layout reduces contamination and improves workflow efficiency.

Lesson 3 • Ventilation and Environmental Controls

Details passive and active ventilation strategies, fume extraction, and temperature control. Directly affects both worker safety and resin cure quality.

Lesson 4 • Health Hazards and Exposure Risks

Identifies chemical hazards including skin sensitization, VOC inhalation, and eye exposure. Provides the risk awareness required before any hands-on resin work.

Lesson 1 • Types of Resin Systems

Surveys epoxy, polyester, polyurethane, and UV resins with their distinct properties. Enables informed resin selection based on project demands.

Lesson 2 • Hardeners, Catalysts, and Additives

Explains the role of hardeners, catalysts, and modifiers in controlling cure speed and final properties. Directly impacts mix ratios and product quality.

Lesson 3 • Introduction to Resin Chemistry

Covers polymer chains, curing mechanisms, and molecular structure of resins. Establishes chemical literacy needed for all subsequent material decisions.

Lesson 1 • Mixing Techniques for Uniform Blends

Covers hand-mixing strokes, mechanical mixing, and fold-and-scrape methods to eliminate unmixed pockets. Uniform blends prevent soft spots and tacky surfaces.

Lesson 2 • Mix Ratio Methods and Accuracy

Teaches weight-based and volume-based ratio methods and sources of measurement error. Accurate ratios are the single most critical factor in achieving full cure.

Lesson 3 • Degassing Methods and Equipment

Introduces vacuum chamber degassing, pressure pot casting, and heat-assisted bubble release. Each method is matched to resin viscosity and project type.

Lesson 1 • Mixing and Measuring Color

Covers colorant dosage by weight, color theory for resin mixing, and batch consistency. Precise measurement enables repeatable color matching across production runs.

Lesson 2 • Specialty Effects and Additives

Introduces metallic powders, glow-in-the-dark pigments, glitter, and holographic additives. Each additive requires specific loading rates and mixing sequences.

Lesson 3 • Resin-Compatible Colorants

Distinguishes alcohol inks, pigment pastes, mica powders, and liquid dyes by compatibility and behavior. Selecting the correct colorant prevents cure inhibition and cloudiness.

Lesson 4 • UV Stability and Color Longevity

Addresses UV inhibitors, yellowing mechanisms, and colorant lightfastness ratings. Ensures finished pieces retain color fidelity under ambient and UV light exposure.

Lesson 1 • Mold Release Agents and Surface Prep

Explains wax, PVA, and spray release agents and their application sequences. Correct release preparation prevents adhesion failures and surface defects.

Lesson 2 • Rigid Mold Materials

Covers polyurethane foam, fiberglass, and machined materials for rigid mold construction. Rigid molds suit high-volume production and large flat castings.

Lesson 3 • Mold Design Principles

Covers draft angles, parting lines, undercuts, and venting for successful demolding. Good mold design prevents part damage and extends mold service life.

Lesson 4 • Silicone Mold Making

Teaches tin-cure and platinum-cure silicone selection, mixing, and pouring for flexible molds. Silicone molds capture fine detail and release cleanly without release agents.

Lesson 1 • Open Pour and Flood Casting

Covers single-layer open pours for coasters, trays, and flat panels. Establishes baseline pour control before advancing to complex multi-layer work.

Lesson 2 • Demolding and Initial Inspection

Guides safe part removal, flex-demolding for silicone, and initial defect assessment. Early defect identification informs finishing decisions and process corrections.

Lesson 3 • Multi-Layer and Gradient Pours

Covers timing windows for inter-layer adhesion, color gradients, and translucency effects. Builds compositional control for decorative and functional multi-layer pieces.

Lesson 4 • Deep Pour and Thick Casting

Addresses heat management, layer thickness limits, and slow-cure resins for deep castings. Prevents cracking, yellowing, and exothermic runaway in thick sections.

Lesson 1 • Polishing Compounds and Machines

Introduces cutting compounds, polishing pads, and rotary vs. orbital polishers for resin. Correct pad and compound pairing determines final gloss level.

Lesson 2 • Wet Sanding Progression

Covers grit progression from coarse to ultra-fine wet sanding for resin surfaces. Systematic grit steps prevent deep scratches from carrying through to the final polish.

Lesson 3 • Cured Surface Assessment

Teaches identification of surface defects including fish eyes, pinholes, scratches, and amine blush. Accurate diagnosis determines the correct finishing sequence.

Lesson 4 • Topcoat and Sealing Options

Covers resin flood coats, UV-cure topcoats, and spray lacquers as protective finish layers. Topcoats extend surface durability and restore gloss after sanding.

Lesson 1 • River Tables and Large-Scale Pours

Covers wood preparation, dam construction, deep-pour sequencing, and leveling for river table projects. Combines mold, casting, and finishing skills at production scale.

Lesson 2 • Project Planning and Material Estimation

Teaches volume calculation, material cost estimation, timeline planning, and risk assessment for resin projects. Systematic planning reduces waste and prevents mid-project failures.

Lesson 3 • Quality Control and Defect Prevention

Establishes inspection checkpoints, defect root-cause analysis, and process documentation for consistent output. Quality systems distinguish professional production from ad hoc work.

Lesson 4 • Functional and Structural Resin Parts

Addresses fiber reinforcement, post-cure schedules, and mechanical property optimization for load-bearing parts. Extends resin use beyond decorative into functional applications.
