Lesson 1Hardener selection an resin-to-hardener ratios — stoichiometry, measuring accuracy, an effects of ratio errorsExplore how hardeners control cure speed an final properties. Yuh wi learn correct resin-to-hardener ratios, how fi measure by weight or volume, mix thoroughly, an recognize, prevent, an troubleshoot ratio an mixing errors.
Stoichiometry basics fi two-part resin systemsChoosing slow, medium, or fast hardenersWeighing versus volume measuring techniquesMixing procedures fi avoid unmixed streaksSymptoms an fixes fi off-ratio resin curesLesson 2Basic first aid an emergency response fi resin exposure, skin contact, an inhalationDis section outline basic first aid an emergency steps fi resin exposure. Yuh wi learn how fi respond to skin an eye contact, inhalation of vapors, accidental ingestion, an large spills, an when fi seek professional medical help.
Recognizing early signs of sensitizationImmediate steps fi skin an eye exposureResponding to inhalation an breathing issuesHandling accidental ingestion incidentsSpill response, containment, an reportingLesson 3Choosing de right resin system fi small-batch crafts: viscosity, working time, yellowing resistance, an food-safety considerationsLearn how fi select resin systems fi small-batch crafts by comparing viscosity, working an cure times, yellowing resistance, an food-contact safety. Understand labels, certifications, an trade-offs between clarity, hardness, an durability.
Reading resin technical data sheets an labelsViscosity, self-leveling, an bubble releaseWorking time, gel time, an full cure windowsUV stability, yellowing resistance, an clarityFood-contact claims, tests, an safe use limitsLesson 4Comparison of resin types: epoxy, polyester, an UV-curable resins — properties, pot life, cure behavior, an typical applicationsCompare epoxy, polyester, an UV-curable resins fi craft use. Yuh wi examine odor, toxicity, cure speed, shrinkage, clarity, hardness, an pot life, an match each resin type to molds, coatings, jewelry, an odda small-batch projects.
