Bulk Mixing Materials & Equipment

materials resin components all carbon two part resins are made by combining two components part a & part b part a is highly viscous, similar to honey it contains photosensitive chemicals so it must be stored in an opaque container part b is lower viscosity than part a, similar to vegetable oil it can be stored in clear or translucent containers in some cases, other substances may be added to part a or part b for example docid\ gwpcplgv72h6vu9jvbci4 requires huntsman jeffamine d230 to be added to epu 46 part b epu 46 color base part a requires pigment dispersions to be added to achieve the desired color downpacking by their nature, bulk resins come in large packages and can be quite heavy to move by hand large drums and ibcs require equipment for safe transport additionally, part b components are much less viscous (more watery) than part a so they will pour much faster and are more difficult to control when using larger containers for these reasons, downpacking is recommended for large package volumes consider downpacking to 5 l, 3 6 l, or 1 l containers to dispense components much easier container size considerations spouts all bulk containers a spout spout can be useful for down packing select a cap/spout for the container size that you use from your preferred industrial supply retailer bulk container spouts if the spout contains clear plastic housing clear plastic housing , this can lead to premature resin curing and can clog the spout and affect part quality cover the housing with duct tape, foil or another opaque material to protect the resin from light exposure part a considerations the part a component is light sensitive, so it must be stored in light proof containers like opaque amber nalgenes due to its high viscosity, part a components are better suited to be stored in containers with wide mouths part b considerations the part b component is not light sensitive, so it can be stored in any color ppe or hdpe bottle due to its low viscosity, part b components work best with narrow mouth bottles in order to have better control of the material during pouring carbon recommends immediately down packing rpu 130 part b and epu 41 part b into 1 l bottles to make handling easier, safer, and avoid “salt” formation handling tipping mechanisms can be useful for drums if you use them frequently a pump is generally not advised with resin as cleaning and maintenance of pump components can be burdensome drum tipping pigments epu 46 color base part a enables the creation of a wide range of custom colors coloration is achieved by mixing a range of pigments into part a only validated pigments can be used for color creation see docid 74h6ie6gvincnbscz0r9l for more information colored pigments equipment mixer the mixer is the main piece of equipment required for blending resin components these mixers are compatible with carbon's two part materials vortex mixer overhead mixer planetary mixer mmd (meter mix and dispense) mixers go to docid 0qvlfongogoxo dwmyxz4 for general information about the strengths of each mixing option calculator or computer a calculator or computer is needed to calculate the correct amount of each component to measure out information such as the resin type, density of the resin and a\ b ratio by weight is required a computer gives access to the docid\ ehr4rn9ypf660igj3vprp which provides a user friendly interface for calculating resin amounts precision scale a high precision scale accurate to at least 0 2 g is required consider maximum weight capacity for your printer/application

and storage easier part a components must be stored in opaque containers to protect contents from exposure to light different sizes of nalgenes plastic containers plastic containers (hdpe or polypropylene) can be used to store components purchased in higher volume packaging part b components are not light sensitive so they can be stored in clear or natural containers due to the low viscosity of part b, narrow mouth bottles are a good fit the smaller opening makes it easier to pour accurately various plastic containers narrow mouths work well for pouring part b part a contains photosensitive chemicals and so must be stored in opaque containers mixing containers high density polyethylene (hdpe) and polypropylene (pp) are used for the packaging of carbon resins and are recommended to be used for mixing operations as well mixing cups for planetary mixers typically come in 3 parts cup, inner seal and lid pipettes pipettes are used to dispense small amounts of components and pigment dispersions pipettewhen dispensing higher viscocity components like part a, it may be necessary to cut the tip off a pipette silicone spatula spatulas are useful for capturing residual mixed resin left in mixing containers silicone spatula blue paper towels standard disposable shop towels for cleaning up spills and smears blue paper towels
