RAMPF Group Presented Silicone Adhesives at SID Display Week 2018

Published on 2018-06-18. Author : SpecialChem

With a fully automated, partially patented joining method and premium liquid optically clear adhesives, RAMPF Group, Inc. has presented a holistic solution for using optical bonding technology in displays at SID Display Week 2018, May 22 - 24, LA, CA – Booth 732.

Adhesives for Clear, Durable, & Sharp Displays

RAMPF optical bonding adhesives for clearer displays

In automotive cockpits, mobile devices, GPS, industrial monitors, navigation devices, and wearables, state-of-the-art displays must exhibit razor-sharp definition, clarity, high durability, and extended product life. To meet these growing demands, RAMPF Group, Inc. has developed cutting-edge processing technologies and silicone adhesives

RAMPF DC-VAC Vacuum Dispensing System


RAMPF has developed a fully automated, partially patented joining method that ensures the reliable, bubble-free application of bonding materials with subsequent joining of components. This cuts the scrap rate to nearly zero. The bonding material is applied in a vacuum and the components are joined in an airless environment. The thin-film degassing technology of the single components makes it possible to process bubble-free bonding material.

Bubble-free Bonding Application


Degassing of undercuts and the gap between the frame and display is also performed while the material is being applied. This minimizes the risk of air bubbles being trapped during the joining and curing processes. The bonding material is dispensed by the RAMPF DC-VAC Vacuum Dispensing System. Designed for processing one- and two-component casting materials, the cell is equipped with material conditioning under vacuum and the dynamic mixing system MS-C.

The vacuum chamber has large windows to check and adjust the encapsulation process. Various monitoring options guarantee full process control. The vacuum chamber can be designed for manual or automatic part loading.

The DC-VAC is combined with:

• C-DS gluing units
• Assembly units 
• Robot systems 
• Conveyor systems
• Process control systems to a fully automated, customized production system.

In addition to the display joining method in a vacuum, RAMPF’s fully automated production system also features all the operations to bond displays to frames.


RAKU® SIL Silicone Adhesives


RAKU® SIL silicone adhesives from RAMPF boast outstanding optical and mechanical features:

  • 100% transparency / transmission
  • Total clarity, very low haze value
  • Stable color values throughout the entire service life
  • Varying hardness levels VLRH 20 to VLRH 95
  • Excellent adhesion

RAMPF adhesives deliver unbeatable value for the money and are optimized for industrial-scale processing on mixing and dispensing systems. They cure at room temperature and are available in various hardness and viscosities (from liquid to thixotropic).

RAMPF Group Range of Adhesives


RAMPF Group, Inc. also offers high-class adhesives for attaching displays, frames, supports etc. When used in combination, they are also ideal for the dam and fill process, in which a dam is filled with a highly viscous adhesive that keeps the free-flowing optical adhesive in place and, after joining, also helps adhesion.
