coat weight control

The CWC system primarily relies on a camera as its main sensor to analyze the amount of glue weight applied to a surface. The camera captures visual input, which is used to determine the grams per square meter measurement of the glue. However, the camera’s view is cropped, meaning it focuses only on the direct beam of glue exiting the glue gun during operation, rather than a full square meter area. As a result, the camera measures the total amount of glue applied when scaled up to a square meter area. The standard warning system of the CWC system is designed to provide feedback to the operator. When the system is turned on and running, the lamp on top of the camera emits a blue light, indicating that the system is in warning mode and detecting an insufficient amount of glue. At this point, the operator can start using the glue gun. If the amount of glue detected by the camera falls within the range of 25-35 grams per square meter, the blue lamp changes to green, indicating that the ideal amount of glue has been applied to the fiberglass surface. However, if the glue weight exceeds 30 grams per square meter, the light turns yellow, signaling that an excessive amount of glue has been applied. The operator may need to either work faster or adjust the glue gun settings to lower the flow output. In cases where the glue weight reaches 45 grams per square meter on the glass fiber, the light turns red, accompanied by a loud warning sound. This indicates that a seasoned personnel should intervene to address the heavy glue application. The settings of the CWC system can be customized/calibrated to suit specific requirements. The thresholds or set amounts for detected glue and the corresponding light bulb colors can be adjusted according to the desired parameters of the glue application

Light Brown Hotmelt Adhesive

Specially formulated for use in vacuum infusion processes for composite production

The vac tac 100® hotmelt spray system is used for positioning reinforcement materials and peel ply layers in the mold prior to resin infusion. It is suitable for positioning glass mat, balsa and foams within the composite structure. The vac tac 100® hotmelt glue system is custom made for the construction of yachts and wind turbine blades. This versatile, safe and solvent-free hot melt technology delivers higher levels of tack than is possible with traditional aerosol cans. Once applied, it remains tacky for up to 4 minutes so that core materials can be positioned and adjusted – giving the user more time and flexibility to work. The high levels of tack reduce the amount of adhesive required. This minimizes both the cost, and the risk of impacting the composite structure.

Vac tac 100® hot melt spray adhesives have been specially formulated for use with vacuum infused composites, to position and secure reinforcement fabrics, foams, balsa, peel plies and release films during lay-up – even in the largest vacuum infused composite structures. They only need to be applied to one surface using vac tac 100® spray tools, where, for up to 4 minutes, they provide an instant, very high ‘grab’ adhesive surface. Once attached, the materials can still be easily repositioned if required – offering more working time and flexibility for the user. Only once they have been firmly pushed together is the final adhesive bond made. Unlike VOC (volatile organic compound) spray adhesives, vac tac 100® has an unlimited shelf life and does not require any special packaging, transportation, or storage. When applied correctly, vac tac 100® has none of the health and contamination problems normally associated with airborne particles produced by other adhesives, and is 100 % solvent- and water-free.

Specially formulated for use in vacuum infusion processes for composite production

The vac tac 100® system contributes to fast, efficient, non -hazardous  work environment that saves time and money.
